3.1.6 Country
Select a country in this menu. This is used to set the default values for
pipe diameter and insulation thickness. For more information see
Appendix 5.1, page 24.
3.1.7 Maintain temperature
The maintain temperature is the water temperature that you set for normal
use. The temperature can be selected using the up/down arrow keys.
The minimum temperature is 41˚C or the economy temperature, whichever
is higher. The maximum temperature depends on cable type, pipe thick-
ness, insulation thickness and ambient temperature (see Fig. 3, page 12).
The programmed maintain temperature can be displayed by pushing the
escape key once the system is in operation.
3.1.8 Economy temperature
The economy temperature is the water temperature for periods during
which hot water is not usually tapped (at night) or when lots of hot water
is tapped (peak period). The temperature can be selected using the
up/down arrow keys. The minimum temperature is 41˚C and the maximum
temperature is the selected maintain temperature.
3.1.9 Pre-Programs
The HWAT-ECO has 8 default timer programs. See 5.5.2 Diagrams,
page 35 for more information. A pre-program can be selected using the
up/down arrow keys. Press Enter to confirm your choice. HWAT-ECO takes
a few seconds to copy the default program to the internal memory. During
this time a row of dots will show in the display.
